What is the test for a plaintiff to bring an action for damages based on an allegedly unconstitutional conviction or imprisonment?

Additionally, before plaintiff may bring an action for damages based on an allegedly unconstitutional conviction or imprisonment, or for other harm caused by actions whose unlawfulness would render a conviction or sentence invalid, plaintiff must prove certain elements. Plaintiff must prove that the conviction or sentence has been reversed on direct appeal, expunged by executive order, declared invalid by a state tribunal authorized to make such determination, or called into question by a federal court's issuance of a writ of habeas corpus. Heck v. Humphrey, 512 U.S. 477, 486-87 (1994).
